What Is Hand, Foot, and Mouth Disease?

As of September 2026, Hand, foot, and mouth disease is caused most commonly by enteroviruses, particularly the coxsackievirus A16 and enterovirus 71. These viruses are highly contagious and spread through contact with an infected person’s saliva, nasal mucus, or feces. The disease is most common in young children, but adults can also contract it, especially in environments with close contact like schools or daycare centers.^[2]

The symptoms of hand, foot. Mouth disease typically appear within 3 to 7 days after infection and include a sudden fever, sore throat, and the development of painful sores or blisters on the hands, feet, and inside the mouth. These blisters can be particularly uncomfortable, making it difficult for young children to eat, drink, or even speak without pain.

While the condition is usually mild and resolves on its own within 7 to 10 days, it can be severe in rare cases, especially when caused by enterovirus 71. In these cases, complications like meningitis or encephalitis can occur, which is why early identification and monitoring is crucial.^[3]

How Is Hand, Foot, and Mouth Disease Diagnosed?

Most cases of hand, foot, and mouth disease are diagnosed through a physical exam and a review of symptoms. A healthcare provider will look for the characteristic blisters on the hands, feet, and inside the mouth. In some cases, especially if the symptoms are severe or the patient is young, a lab test may be performed to confirm the presence of the virus.

Lab tests for hand, foot, and mouth disease may involve taking a swab from the back of the throat or from the blisters on the skin. These swabs are then analyzed in a lab to detect the virus. This is more common in hospital settings or when the disease is suspected to be caused by a more serious strain like enterovirus 71.

In some cases, blood tests may also be used to detect antibodies to the virus. These tests are not always necessary for mild cases, but they can help rule out other serious conditions and guide treatment decisions.

Early diagnosis can make all the difference in preventing complications from hand, foot, and mouth disease.

How Is Hand, Foot, and Mouth Disease Treated?

There is no specific treatment for hand, foot, and mouth disease, but managing the symptoms can help ease discomfort and speed up recovery. The most important aspect of treatment is ensuring that the patient stays hydrated, as the pain from the sores can make drinking water difficult.

Over-the-counter pain relievers like acetaminophen or ibuprofen can help reduce fever and relieve pain from the blisters. In some cases, especially for young children, a doctor may recommend a special mouth rinse or pain-relief gel to apply to the sores.

It’s also important to rest and avoid contact with others to prevent the spread of the virus. In severe cases, hospitalization may be necessary to monitor for complications like dehydration or respiratory issues.

How Long Does Hand, Foot, and Mouth Disease Last?

The average duration of hand, foot, and mouth disease is around 7 to 10 days, though some people may recover faster and others may take longer. The initial symptoms — such as fever and sore throat — usually last for 3 to 5 days before the blisters and sores begin to form.

The blisters typically peak around day 5 to 7 and start to dry up and form scabs. The scabs then fall off within a few days, leaving no permanent scars. However, the healing process can be uncomfortable, especially for young children who may struggle with pain and dehydration.

In most cases, the body’s immune system clears the virus within 7 to 10 days. However, if the infection is caused by a more severe strain like enterovirus 71, the recovery time may be longer and require more medical attention.

How Can You Prevent Hand, Foot, and Mouth Disease?

The best way to prevent hand, foot, and mouth disease is to practice good hygiene. This includes washing hands frequently with soap and water, especially after using the restroom, before eating, and after changing a diaper. It’s also important to avoid sharing personal items like utensils, towels, or toothbrushes with someone who is infected.

In environments where children are in close contact — such as daycare centers or schools — it’s important to be vigilant about outbreaks. If an outbreak is reported, parents should take extra precautions, such as keeping their children home if they are sick and ensuring they stay away from other children until they are no longer contagious.

In some cases, especially in high-risk communities, healthcare providers may recommend vaccination against certain strains of the virus. While there is no specific vaccine for hand, foot, and mouth disease, vaccines for other enteroviruses may provide some level of protection.

How Is Hand, Foot, and Mouth Disease Different From Other Rashes?

Hand, foot, and mouth disease is often mistaken for other viral rashes or skin conditions, such as chickenpox or eczema. However, the key difference is that hand, foot, and mouth disease is caused by a specific group of viruses called enteroviruses and typically presents with blisters on the hands, feet, and inside the mouth.

In contrast, chickenpox typically causes a widespread rash that appears all over the body, including the face, torso, and limbs. Eczema, on the other hand, is a chronic skin condition that causes dry, itchy patches and is not contagious. It’s important to differentiate these conditions to ensure proper treatment and care.

If you or your child develops a rash and other symptoms like fever or sores in the mouth, it’s best to consult a healthcare provider for a proper diagnosis. Early identification can help prevent complications and provide relief from the discomfort of the illness.

Don’t confuse hand, foot, and mouth disease with other rashes — the symptoms are different and the treatment is unique.

How to Cope with Hand, Foot, and Mouth Disease at Home

Coping with hand, foot, and mouth disease at home can be challenging, especially for young children who may be in pain and unable to eat or drink comfortably. However, with proper care, most people can recover without complications. The most important thing is to manage the symptoms and stay hydrated.

Pain from the sores can be managed with over-the-counter medications like acetaminophen or ibuprofen. It’s also important to avoid spicy, acidic, or salty foods, which can further irritate the sores. Offering cool, bland liquids like water or apple juice can help soothe the mouth and prevent dehydration.

Rest is also important, as the body needs time to fight off the virus. Keeping the infected individual away from others can help prevent the spread of the virus. In most cases, with proper care, the body will recover within 7 to 10 days.
